Store on the counter. Move any uneaten apples to the refrigerator after seven days. In the fridge or out, don’t store near most other uncovered fruits or vegetables — the ethylene gases produced by apples can ruin them (making carrots bitter, for example). The exception: if you want to ripen plums, pears and other fruits quickly, put an apple nearby for a day or so.
Store upright in the refrigerator in a plastic bag with either an inch of water or with a damp towel wrapped around the base, just like you would have flowers in a vase. They’ll last three to four days that way.
Ripen on the counter. Can be stored in the refrigerator for three to four days once ripe. A clever trick: ripen a hard avocado by sticking it in a paper bag with a banana.
Unwashed and in their original container. Blueberries and strawberries should keep for five to seven days; more fragile raspberries and blackberries up to two days.
Keep in the front of the refrigerator, where it’s less apt to freeze.
